OPERATING-TABLE. Y

To all icl-tom 'it-may concern l Be it known that 1,' FRANK ZAMCNIK, a citizen of the RepublicV of Czechoslovakia,

who has declared his intention of becoming utility and efficiency of tables of this class.

' Another'object of the invention is to provide a table of this class. which will be comfortable tol the patient, automatically adjustable to the movements of the patient under treatment, and ywhich will also :au-V

tomatically adapt itself to the degree of pressure applied by the practitioner.

With the-se and other objects in view, the invention consists in certain novel features of construction ashereafter shown and described and then specifically pointed out inthe claims, and in the drawings illustrative of the preferred embodiment of the invention: y Y

Figure 1 is a side elevation, partly in section, of the improved table.

Fig. 2 is a plan view.

Fig. 3 is an elevation of the foot end of the improved table. j

Fig.'4 is a transverse section on the line 4-4 of Fig. 1.

Fig. 5 is a plan view with the cushions removed.

Fig. 6 isa sectional detail illustrating a modification ina portion of the construction.

Figs. 7 and 8 are detail views on a reduced scale illustrating another modification in the construction. j

The improved table comprises a head frame formed of corner posts 10, connecting upper stringere 11 and lower stringere 12, a foot frame formed Aof corner posts 13, upper connecting stringers 14 and lower stringers 15, the head and foot frames being connected near their lower ends by longitudinal stringers 16.

The head frame is formedV with its upper lines sloping downwardly toward the foot and supports plates 17 in spaced relation Specication of ietters (Patent.

lAipplication 1ed 0ct`ober`20, 1920. Serial No. 418,204.

and cushioned, as shown at 18, the' object to be hereafter explained. l t The upper lines of the foot frame are preferably horizontal, and resting upon the posts 13`and the upper stringers 14 is a plate or board 19, the 'latter cushioned, as

shown at 20. v

Y The plate '19 is hingedly connected to the posts V13 nearest the head` frame, as shown at 21, so that it can be tilted as shown by dotted lines in Fig. 1. The hinges'21'have detachable pintles 22, so thatthe board'can easily be detached to provide access to the spring mechanism when required.

The lower stringers 15 of the foot frame support a-loor member'23, while .the space between` the posts 13 Aand .stringere-14 and 15 areV filled with panels 24 and atransverse partition 25 to form a cabinet or receptacle, the yrear anelbeing' hinged at 26 to form a door to t ecabinet.

head :frame is a headv member 28 for a bar 29, the latter extending toward the .foot frame, as shown.V Attached byy screws 30 or the like to the bar 29 at its Vfree end is a board ory plate 31 having a cushion 32 on its upper face. `The plate V31` is widest at its rear end and convergesy towardv theforwardend, as shown in Fig. 2.

Attached by screws 33 or thelike to-the under face of the plate 31 'are extension bars 34, the latter extended at ltheir free ends beneath the adjacent portion ofthe plate 19 and provided with wear plates 35.'

Hingedly united at 36'to the" adjacent membernll of the head frame isa shorter plate 37 resting by itsjfree end `upon the bar 29 having an upholstered top 38, preferably supported yby springs 39, as shown provided with a shorter member 45 spaced from the bar, and the shorter members connected by transverse supports 46.

The longer bars 43, shorter bars 45 and coupling members or supports 44 and 46 coact to form a relatively rigid frame swinging upon the pivots 42.

Mounted within the spaces between each of the bars 43 and its shorter bar 45 is a cam device 47, and extending from each cam device is a rod 48 terminating in a head or enlargement 49 and surrounded by a compression spring 50. .The springs are relatively powerful and exert their force in coaction with theV cam devices to maintain the bars 43 yieldably in a horizontal position, and correspondingly hold the larger bars 29 and 34 together with the plate 31 and cush ion'32 yieldably in substantially horizontal position, andto automatically return them t0 normal position when released.

An additional expansion spring 51 isconnected to one of the transverse members 46, and operates t0 supplement the action of the springs 50. v

The plate 37 and its cushion 39, beingr supported by the bar 29, are moved upwardly and downwardly therewith, as` will be obvious.

By this means supporting cushions 32 and 38 are yieldably supported and are returned automatically to their normal position when released.

The rear plate 19 and its cushion member 2O have a recess 52 in the Yforward edge to protect certain parts of the patient during certain manipulations of the operator.

Attached to the upper transverse member or support 46 is a knob or projection 53 adapted to engage the board or plate 19 when the bars 29 and 34 with their attached cushion 32 are depressed against the resistance of the springs 50 and 51 to swing the free end of the member 19 and its cushion 20 into the positionshown by dotted lines in Fig. 1. This is an important feature of the improved table, as when the patient lies face down on the table, with the face upon the cushion members 18, the posterior region above the cushion 32, and the lower limbs upon the cushion 20, when pressure is applied to the lower part of the spinal column, the support 32 will yield downwardly and relieve the patient of undue jars orv concussions, while at the same time the lower limbs `,will naturally rise when `the intermediate signature.

body portion is depressed, and by providing means whereby the supporting member 20 follows the lower limbs in their upward movement, the latter are eifectually supported at all times.

The upward movement of the support 2O corresponds to the downward movement of vthe support 32, so that they coaet to adequately support the body of the patient during all stages ofthe treatment.

Vhile I have shown the springs arranged and applied beneath the free end of the eX- tension members 34, they may beflapplied near the swinging end, as shown in Fig. 6

Vor at anyother point desired.

The springs may Aalso `be applied `as shown in Figs. 7 and' 8. I

What is claimed is: 7 1. A table device of the class `described comprising a forward body support, a rear body support, a forward intermediate body support, a rear intermediate body support, means for yieldably supportingsaid intermediate body support, and means whereby the depression of the intermediate body sup# ports causes'the elevation of the rearsbody support. i

2. A supportinoframe includingforward and rear standar s in spaced relation, a forward body supp'ortupon said forward standard, a rear body support `hingedly united to saidrear standard, a bar swinging at one end from the forward standard and extended toward the rear standard, anintermediate bodysupport hinged atv one end to said forward standard and bearing at its free vend upon said bar, another intermediate body support attached to said bar, and yieldable means for holding said bar and its attached body support in its upper position. 3. A table device of the' class described comprising a forward bodyesupport, a rear body support a forward intermediate body support, a rear intermediatebody support, means for yieldably supportingsaidintermediate body support, and meanswhereby the depression of the bar causes the rear body support to be elevated.
